4.1.3.7 panic (Kernel-Destructive)

void panic(void)

When triggered, the panic action causes a
kernel panic. This action should be used to force a system
crash dump at a time of interest. You can use this action
along with ring buffering
to understand a problem. For more information, see
Chapter 5, Buffers and Buffering
. When the panic action is used, a panic
message appears denoting the probe that is causing the panic.
rsyslogd also emits a message upon reboot.
The message buffer of the crash dump contains the probe and
event control block (ECB) that is responsible for the
panic action.
